- Actin Binding Protein Spin-Down Assay Kit详细信息：
- Product Uses Include
- To determine whether a protein binds to filaments or monomers of actin.
- To determine whether a protein bundles F-actin
- To test various conditions (e.g. pH optima) or requirements (e.g. divalent cation requirement) for binding to actin
Actin Binding Protein Spin-Down Assay Kit Introduction
The actin binding protein spin-down assay kit provides G- or F-actin plus positive (α-actinin ) and negative (Bovine Serum Albumin, BSA) binding control proteins. Actin binding occurs when there is an affinity for any site of actin. F-actin binding can be measured by using a spin down method. In this way centrifugation is used to separate F-actin from G-actin by differential sedimentation. F-actin binding proteins will co-sediment with actin filaments and form a pellet at the bottom of the centrifugation tube. Proteins with F-actin bundling activity can be detected since they will cause the F-actin to sediment at lower centrifugal forces than normal (14,000 x g vs 150,000 x g). F-actin severing proteins, G-actin binding proteins or non-actin binding proteins will stay in the supernatant. Severing proteins will be expected if more G-actin remains in the supernatant than in the negative control sample, and this activity should be tested further by measuring F-actin length distributions before and after adding the test protein. G-actin binding proteins can be measured by adding the test protein to G-actin and inducing polymerization, if the test protein sequesters G-actin then during the spin-down assay more actin will be left in the supernatant compared with the control.
